I am using macOS 10.14.5 and all but one of my reminder lists have gone.
I have macOS Catalina Beta installed on a separate testing partition and all my Reminders are there. But they don't appear on my main partition.
Is there any way I can get them back?
I don't have any iOS devices. And when I go to iCloud via the web, it just says Reminders coming soon. I tried restoring Reminders via iCloud on the web, but after the restore, they still aren't present on 10.14.5
